had the car in for its MOT. failed on emissions as stated

car - 1.4 16v 6n

question? - how do i lower the emissions

i warmed up the engine before taking it in i put sum petrol lean stuff in that didnt help.... i changed the spark plugs and airfilter..... not helped

am i right in thinking it could be the lambda sensor? or the Cat convertor if so how much money are we talking to sort them two out ???

all advice i am thankful for in advance..

Did you try this http://www.halfords.com/webapp/wcs/stores/...tegoryId_165750

I have heard it is really good, when you put it in you have to do a fair few miles before it actually helps to clean the gunk out of the engine! When you put your petrol / engine cleaner in, did you make sure it had been in for at least 3 days?

Hope this helps :)

id try lambda first its only about 60 quid tops i think for one

id pin it on the lambda sensor, my GT failed on emissions on thursday so me and a mate leaned the afm right out to make it pass, new sensor is on order now

How much has it failed by? Alot?

Mine failed on its emissions on my last MOT, I just put a full bottle of petrol magic in, a fivers worth of BP ultimate, kicked it's head and it passed - Just!

Lambda sensors are quite dear like. I've looked on ECP and for a Bosch one you're looking at £70.

have u got the emissions print off if soo tell me you are readings and i can help u out

I managed to get hold of a lamba sensor off here for £15 posted. It might not be that though, mine passed the emissions not long ago, but it still needs a lambda sensor...
